remove unneeded headers

[noelallen1, 2013/09/19 21:29:27]

Done.

+
+#include "nacl_io/fifo_interface.h"
+#include "ppapi/c/pp_resource.h"
+
+#include "sdk_util/macros.h"
+
+namespace nacl_io {
+
+class PepperInterface;
+
+// NOTE: The Packet class always owns the buffer and address, either by 'Copy'
+// or by 'Take' ownership.
+class Packet {
+ public:
+  explicit Packet(PepperInterface* ppapi);
+  ~Packet();
+
+  // Copy the buffer, and address reference
+  void Copy(const void *buffer, size_t len, PP_Resource addr);

turn this into an alternate constructor?

[noelallen1, 2013/09/20 00:51:27]

Going to circle back on this.

+
+  // Take ownership the buffer, and address reference
+  void Take(const void *buffer, size_t len, PP_Resource addr);

[binji, 2013/09/19 00:48:55]

unused. Remove?

[noelallen1, 2013/09/19 21:29:27]

I was using this... I'll dbl check and remote.  Originally I need to construct
the packet and Copy or Take.

+
+  char* buffer() { return buffer_; }
+  PP_Resource addr() { return addr_; }
+  size_t len() { return len_; }
+
+ private:
+  PepperInterface* ppapi_;
+  PP_Resource addr_;
+  char* buffer_;
+  size_t len_;
+
+  DISALLOW_COPY_AND_ASSIGN(Packet);
+};
+
+}  // namespace nacl_io
+
+#endif  // LIBRARIES_NACL_IO_PACKET_H_
